Jefferson had some explicitly white separatist views: he famous said that whites and blacks must be equal, but that they would not be able to live together in peace.

“Nothing is more certainly written in the book of fate than that these people [blacks] are to be free. Nor is it less certain that the two races, equally free, cannot live in the same government. Nature, habit, opinion has drawn indelible lines of distinction between them.” –Thomas Jefferson

“Among the Romans emancipation required but one effort. The slave, when made free, might mix with, without staining the blood of his master. But with us a second is necessary, unknown to history. When freed, he is to be removed beyond the reach of mixture.” –Thomas Jefferson

So here I present a fascinating problem in the culture and politics of the United States of America. To be a good USA citizen, one must be implicitly Jeffersonian. In theory, this means that anyone, of any race or color, can subscribe and mentally assent to the principles of the Founding Fathers and join the struggle for nomocracy, minarchy, Enlightenment, etc.

And yet in practice, while Jefferson believed blacks must be free, he believed that they had to be free in a separate community from whites.
